Description

Knee dynamic foot drop and hemiplegic gait aid

Technical Field

The utility model relates to the technical field of medical rehabilitation equipment, in particular to a knee dynamic foot drop and hemiplegic gait assistor.

Background

The hemiplegic gait which is mainly characterized by the ring-drawing gait is left for the hemiplegic gait of the patient with the hemiplegic paralysis after the stroke often due to the abnormal movement mode (the extensor mode of the lower limb) and the unbalanced muscle of the lower limb (the drop foot caused by the high tension of the triceps surae and the weak tibialis anterior muscle), which is mainly characterized in that the thigh is not bent sufficiently in the forward direction during the stepping, the ring-drawing posture drives the lower limb to move forward by lifting the pelvis and the hip joint to expand outwards, and meanwhile, the bad load-bearing conditions such as the foot varus, the knee hyperextension and the like occur in the supporting process of the affected leg, thereby seriously affecting.

The ankle-foot orthosis (AFO) is commonly used clinically to correct the problems of foot drop and foot varus, and has a certain inhibiting effect on knee hyperextension, but the AFO only aims at the ankle joint, cannot adjust the overall motion mode and coordinated motion of hip, knee and ankle joints, and a patient still has abnormal gait. Meanwhile, the AFO has problems of excessively restricting ankle joint movement, inhibiting input of plantar sensation, and the like. Although dynamic ankle AFO may allow some patients to perform their own ankle-dorsal extension function. But still limits the plantarflexion function of the ankle joint, and simultaneously, part of the ankle dorsum of the patient is weak, so that the ankle dorsum of the patient cannot normally exert the ankle dorsum function in the walking cycle, thereby causing the function of the ankle joint of the patient to be degraded.

An auxiliary device capable of correcting gait of hemiplegic patients also appears in the market at present, for example, a knee dynamic radian pulley type foot drop and hemiplegic gait corrector with Chinese patent publication No. CN105997320B comprises a knee thigh correcting component, a thigh correcting mechanism fixing component, a shank correcting component fixing component, a crank lever component, a foot support connecting rope and a foot support … ….

However, in actual rehabilitation training, particularly in the early stage of rehabilitation treatment of a stroke patient, the patient often has difficulty in lifting the lower limbs by himself, and generally needs to assist by others through external force to achieve the effect of walking freely, and the assistance by others is troublesome, cannot be accurately consistent with the side-walking rate, is limited in movement, and has certain defects.
